Background technology
Smoke dust sampling is the important step of soot emissions, equipment performance experiment and environmental protection supervision.To dedusting, desulfurization,
When measuring point smoke content after denitration device is sampled, it is necessary to using smoke dust sampling device.According to relevant national standard, flue dust
During sampling need to according to flue size to determine sampling location, such as roomy air flue soot dust sampled when, same radial direction can deposit
There is strict demand in multiple sampling point positions, therefore to sampling gun length.But long sampling gun is both unfavorable for processing and ensureing
Gun body intensity, also it is not easy to be adjusted in time according to the size of roomy flue, simultaneously because place limits, long sampling gun is not easy to transport
It is defeated.
Traditional smoke dust sampling carries out flue dust collecting using glass fiber filter cylinder, when carrying out dry flue gas smoke dust sampling, often
Because flue-gas temperature is too high, filter cylinder is caused to become fragile.It can be produced when taking out filter cylinder and leave many chips, so as to be weighed in filter cylinder
When there is measured deviation；And in wet flue gas smoke dust sampling, because the internal and external environment temperature difference of sampling gun is larger, the water in wet flue gas
Mix, sampling gun inside can be corroded with the acidic materials in flue dust and flue gas after dividing condensation, or even block air flue, simultaneously
Also sampling filter cylinder can be made to get wet softening, or even rupture, the filter cylinder after smoke dust sampling is influenceed and weigh.
